Capt. Kevin Hamilton, commander of the detective division, has been named acting police chief by City Manager Joe Felz.

Felz, in a statement released Wednesday afternoon, said Sellers' doctor initiated having him placed on medical leave.

In 30 days, Sellers' physician will contact Felz with an assessment of the chief's condition along with a recommendation on when, or if, he can return to work, the city manager said. Felz said he didn't have details on the chief's medical condition.

"This is not a permanent thing," Felz said. "Our goal is to move forward and continue to move forward."

Hamilton, 53, has been a Fullerton police officer since 1979 and served in several divisions, including patrol, traffic investigation, narcotics, SWAT and the detective bureau. He made the rank of captain in 2010.

The acting chief wasn't making any public statements Tuesday, said Sgt. Andrew Goodrich, the department's spokesman. Hamilton will conduct interviews with the media on Thursday, Goodrich said.

In the city press release, Hamilton did say that Fullerton has "very important issues we have to deal with in light of the Kelly Thomas incident, and we will work with investigators from the District Attorney's Office and the FBI, who are looking into the incident."

His "top priority and responsibility is to police the city,'' Hamilton said. "That's our job, and I will make sure we do it."

Many in the community have expressed outrage about a July 5 incident in which Thomas, a mentally ill, homeless man, was confronted by six officers at the Transportation Center after a report of car burglaries. Police say he resisted officers; Kelly suffered injuries that he died from five days later.

"I am concerned for his health," Quirk-Silva said. "I really, sincerely am. I do understand the turmoil and devastation for him."

Sellers, 59, will continue to be paid his annual salary and benefits package of $228,576. He has served as Fullerton's chief since May 2009. He previously served as chief in Laguna Beach and Seal Beach.
